REFRESHING MOISTURE...

AS NATURE INTENDED

Congratulations on your excellent choice and sound investlnent

in this addition m your holne COlnfortsystem.

Your hulnidifier represents both the latest in engineering devel-

oplnent and the cuhnination of lnany years of experience t}Oln

one of the lnost reputable lnanufacturers of comfort systems.

Your new unit is alnong the most energy-efcient and reliable

holne hulnidifiers available today. To assure its dependability,

spend a few lninutes now with this booklet. Learn about the op-

eration of your hulnidifier and the small alnount oflnaintenance

it takes to keep it operating at peak efficiency.

With lninilnal care, your hulnidifier will provide you and your

_amily with lnoist, spring-fresh air froln season to season and

year to year.

YOUR HOME HUMIDIFIER

YOUR HOME CAN BE DRIERTHAN DEATH VALLEY

During the heating season, your holne can becolne uncolnfort-

ably dry. This is because cold winter air holds very little lnois-

rare. When outdoor air is warmed to average rooln telnperamre,

its relative hulnidity £hlls to even lower levels. Refer to Table 1

for a comparison of the levels of relative humidity for a few sam-

ple enviromnents.

Parched air can cause the wood used in the construction of your

house and furnishings to dry, crack, aM split. Draperies and up-

holstery may age prelnaturely. Amaoying static electric shock

and cling are lnore prevalent. Your tlaoat, nasal passages, si-

nuses, and skin are more susceptible to irritating dryness. You

may even have to set the therlnostat higher than otherwise nec-

essary just to feel warm.

MOISTURE MAKES A REFRESHING DIFFERENCE

Proper hulnidity comrol can alleviate problelns caused by exces-

sive dryness. Furnishings and fabrics take on a more lustrous

appearance. Houseplants tl_ive. Static electricity is significantly

reduced in a properly hulnidified home. Your £hmily will breathe

lnore easily and ilnd relief from the cool, drafty feeling coin-

lnonly experienced in overly dry holnes. The additional lnoisture

supplied by your humidifier may enable you to reduce the tem-

perature setting on your therlnostat without any loss of indoor

COlnfort.

HOWYOUR HUMIDIFIERWORKS

Your hulnidifier adds water lnolecules to the air inside your

holne. Although the rate of humidification is variable, it may

exceed one-half gallon of water per hour. That's a healthy drink

for a dry household. The typical process of lmlnidification be-

gins when water flows through the humidifier vah,e and soaks

the large evaporator pad. Hot, dry air [}oln the furnace passes

through the pad and absorbs the water. Then, this lnoisture-laden

air is distributed throughout the house via the ductwork. See Fig.

1, 2, and 3.

OPERATING YOUR HUMIDIFIER

Your new hulnidifier is designed to operate as part of your home

heating system. It will perforln at lnaximuln efciency if these

recolranendations are followed:

• The hulnidifier is comrolled by a hulnidistat. Adjust the

hulnidistat setting according to the outside telnperature. Refer

to Table 2 as a general guide. If after several days, the air in

your home seems too moist, lower the humidistat setting. Con-

densation on single-pane windows indicates excessive mois-

ture. If the air is too dry, increase the setting. Dry throat and

nasal passages indicate dry air.

• All models come with a humidistat. Continuous blower oper-

ation provides for constant hulnidification. It may also contrib-

ute to greater personal COlnfort because continuous blower

operation minimizes telnperature differences throughout the

home. Furtherlnore, a system equipped with an electronic air

cleaner offers the added benefit of full-tilne air filtration.

• Supply- and return-air grilles should not be blocked by items

such as drapes, flmfiture, and toys. Restricted airflow reduces

the efficiency of the humidifier, as well as that of the whole com-

fort system.

• The humidifier unit lnUStbe properly lnaintained on a regular

basis.

STARTUP PROCEDURES

1. Open the saddle valve on the water supply line. (See Fig. 4.)

Set humidistat to the desired relative humidity. (See Fig. 5

and Table 2.)

2. Turn the fimmce on and adjust the therlnostat to a high tem-

perature setting. Be sure that the fitmace blower is operating.

3. Check to see if water is flowing into the humidifier.

• On a Model HUMCCLBP or Model HUMCCLFP humidifi-

er, loosen the thulnbscrew that holds the distributor cover to the

mp of the cabinet. Lift up the distributor cover slightly to lnake

certain that water is flowing from the solenoid valve into the

distributor pan. Do not lift the cover offthe cabinet more than

1 in. when water is flowing. (See Fig. 6 or 7 according to the

lnodel you own.)

water is flowing froln the solenoid valve into the evaporator pad.

(See Fig. 8.)

• On a Model HUMCCSFP hulnidifier, open the side door or

the front cover. If the front cover is opened, hold the pad assem-

bly in place. Check to see if water is flowing from the solenoid

valve imo the distributor pan. (See Fig. 9.)

• On a Model HUMCCWTR unit, look through the window on

front of the unit to see that the evaporator pad is rotating and

water is flowing. (See Fig. 10.)

The Model HUMCCWTR is controlled by a float valve. Turning

off the fimmce will not affect the water flow until float level is

achieved. (See Fig. 11.)

4. Turn off the furnace. When the blower stops, look into the

humidifier to make sure the water is not flowing into the

unit.

5. Replace the cover assembly and *hsten securely.

6. Now, mrn the furnace on and set the thermostat for desired

rooln telnperature.

SHUTDOWN PROCEDURES

To shut down your humidifier, close the saddle vane on the wa-

ter line. Then turn off the humidistat. When set to the OFF posi-

tion, the humidistat shuts offthe electrical power m the solenoid

valve on the humidifier.

NOTE: If your holne comfort system includes cooling, be sure

the water supply to your humidifier is turn ed off during the cool-

ing season. Close the damper located in the bypass duct if one

is installed. If your humidifier is a Model HUMCCWTR, drain

and clean the water pan as described in cleaning procedures.

PERFORMING ROUTINE MAINTENANCE

With the proper lnaintenance and care, your humidifier will op-

erate econolnically and dependably. Maintenance can be accom-

plished easily by referring to the following directions. However,

before perforlning any lnaintenance, consider these ilnportant

safety precautions:

• DISCONNECT ALL ELECTRICAL POWER TO THE

HUMIDIFIER AND FURNACE BEFORE PERFORMING

ANY SERVICE OR MAINTENANCE TO AVOID PER-

SONAL INJURY.

NOTE: THERE MAY BE MORE THAN 1 ELECTRICAL

DISCONNECT SWITCH.

• ALTHOUGH SPECIAL CARE HAS BEEN TAKEN TO

MINIMIZE SHARP EDGES IN THE CONSTRUCTION OF

YOUR HUMIDIFIER, BE EXTREMELY CAREFUL WHEN

HANDLING PARTS OR REACHING INTO THE WNIT TO

AVOID PERSONAL INJURY.

Your hulnidifier has been designed for easy disassembly to sim-

plii_ cleaning and selwicing. Your unit lnUSt be kept clean m

lnaintain its efficiency.

Regular inspection allows you to deterlnine the cleaning sched-

ule best suited to your humidifier's operating conditions. The

frequency for required lnaintenance will depend most upon the

available water supply. In areas where hard water and high lnin-

eral content are prevalent, lnore frequent cleaning and servicing

may be required.

At minimum, the humidifier will need to be cleaned at the be-

ginning of every heating season.

CLEANING PROCEDURES

Models HUMCCLBP, HUMCCSBP, HUMCCLFP, and

HUMCCSFP

1. Turn off all electrical power to the humidifier and fimmce

or fan coil.

2. Turn offthe humidifier's water supply. (See Fig. 4.)

3. Disassemble the humidifier.

• To disasselnble a Model HUMCCSBP humidifier, gently pull

the latch that secures the access panel. Relnove the door and

slide the evaporator pad assembly out of the unit. (See Fig. 8.)

• To disassemble either a Model HUMCCLBP or Model

HUMCCLFP humidifier, first relnove the water supply con-

nection to the solenoid valve. Next, relnove the screw that

holds the distributor cover to the cabinet, and lift offthe cover.

Discom_ect the drain line from the sump and loosen the

thumbscrew(s) holding the sump to the cabinet. Relnove the

sump. Relnove evaporator pad assembly. (See Fig. 6 or 7,

according to the lnodel you own.)

• To disassemble a Model HUMCCSFR the pad assembly can

be relnoved froln the side access door or the front cover. When

relnoving the side door, lift the pad asselnbly up by holding the

tabs and slide the asselnbly out. When relnoving the front cover

on Model HUMCCSFR discomaect the quick comaects m the

solenoid valve, unscrew the 4 screws to the front cover, snap

loose the mp and bottom catches, and lay the front cover aside.

Once the front cover is off; lift the pad assembly up aM twist it

out. The pad assembly consists of 4 parts; the distributor pan,

fralne, sump, and the evaporator pad. Pull the distributor pan

apart from the fralne and the evaporator pad can be relnoved. Do

not force the evaporator pad in or out without relnoving the dis-

tributor pan as this will distort the pad.

4. Clean the humidifier's external COlnponents.

• If your humidifier is a Model HUMCCSBP humidifier, wash

the access door and outlet drain portion of the cabinet. Make

sure the drain is open.

• If your humidifier is a Model HUMCCLBP or HUMCCLFR

wash the distributor cover, sump cover, and cabinet. Be sure the

inlet ports are open and clean. Then, clean the sump with a solu-

tion of detergent and water.

5. Clean the internal colnponents of your humidifier. Wash the

distributor pan with a mild detergent and warm water. Be

sure holes and slots in the pan are clean and unobsmlcted.

Wash the evaporator pad assembly in a detergent solution.

If there are scale deposits on the pad, soak it in ordinary

household vinegar. If the pad is covered by a heavy deposit

of scale, or if the local water supply has high sullhte or cal-

cium content, replace the pad with a new one. Contact your

dealer for replacement part.

6. Reassemble your humidifier.

7. Turn on the electrical power and water supplies. Refer to

the starmp procedures.

BEFOREYOU REQUEST A "SERVICE CALL"

BEFOREYOU CALL FOR SERVICE, CHECK FOR

THESE EASILY SOLVED PROBLEMS:

• Check the lnain power discomaect

switch. Verify that the circuit break-

ers are on and that fuses have not

blown. If you lnUStreset breakers or

replace filses, do so only once. Con-

tact your selwicing dealer for assis-

tance if the breakers trip or the filses

blow a second time.

• If the hulnidity level is too low, check the hulnidistat setting.

Confirln that the saddle valve is turned on. Check the evapora-

tor pad, and clean or replace the pad as necessary. Check water

level in Model HUMCCWTR.

• Check for sufficient airflow. Check the fimmce filter or elec-

mmic air cleaner for excessive accumulations of dirt. Check for

blocked return- or supply-air grilles. Be sure grilles are open

and unobstructed.

• If water drips froln the humidifier, check the drain hose for

kinks or obstructions. If your unit is a Model HUMCCWTR,

dripping may indicate that the float valve requires adjustlnent.

If your colnfort system still fhils to operate properly, contact

your selwicing dealer for troubleshooting and repairs. Specify

your apparent probleln, and state the lnodel and serial nulnbers

of your equiplnent. (You should have theln recorded where

noted in this booldet.) With this inforlnation, your dealer lnay be

able to offer helpfid suggestions over the phone, or save valuable

time through knowledgeable preparation for the selwice call.

REGULAR DEALER MAINTENANCE

In addition to the routine lnaintenance that you perforln, your

humidifier should be inspected regularly by a properly trained

selwice technician. The inspection (preferably each year, but at

least every other year) should include the following:

• Routine inspection of the hulnidifier. Cleaning, if necessary.

Cleaning or replacelnent of the evaporator pad as required.

• A check of all electrical wiring and comaections.

• A check of water comaections to the unit.

• Operational check of the complete colnfort system to deter-

mine acttml worldng condition. Necessary repair and/or adjust-

lnent should be perforlned at this time.

Your selwicing dealer lnay offer an econolnical service contract

that covers seasonal inspections. Ask for further details.

Record the lnodel and serial nulnbers of your new hulnidifier in

the following spaces. This inforlnation, along with the other
